Signs that the throttle needs cleaning, why is it so expensive to clean the throttle in 4s shop?

The signs that the throttle valve needs to be cleaned are generally manifested as increased fuel consumption, unstable idle speed, and car jitter. At the same time, it will be found that it is difficult to start and the acceleration is weak during use. Dirty throttle will affect air intake, resulting in slow throttle response or jamming. The engine throttle of a general automobile is cleaned every 15000 km, and the injector is cleaned every 20000 km.

Why is it so expensive to clean the throttle in 4s shop?

Cleaning the throttle valve in 4S shop is mainly due to expensive working hours. In addition, compressing the maintenance cycle and adding additional maintenance items are also the reasons why 4S stores are expensive. Maybe some car owners think that the 4S shop is more professional than the repair shop, and some car owners think that they must go to the 4S shop for maintenance during the car warranty period, otherwise there will be no warranty. But in fact, in addition to the first insurance needs to be maintained in the 4S shop, the subsequent maintenance can be maintained without going to the 4S shop. As long as you go to a reliable and qualified repair shop for repair, there will be no warranty period.

It should be noted that every time a vehicle cleans the fuel injector, throttle and air intake, it must also clean the three-way catalyst. Cleaning the exhaust of the nozzle and throttle valve alone will aggravate the pollution and blockage of the three-way catalyst, which will be counterproductive in serious cases. Regular cleaning can ensure the normal operation of vehicles and avoid greater failures.
